MultiMac - Model SM -Eddy Current Instrument

Versatile Threshold Selection

Challenging test conditions are made simple with threshold selections that allow complex gating to detect ID/OD and weld sector defects. 3 gates per channel may be set based on All Phase, Sector, Chord or Half Chord thresholds.

Up to 2 Channels 

Two differential (null) or absolute channels, each able to operate over the entire frequency range of 1 KHz to 5 MHz, with appropriate test coils or rotary probes.

EC Screen 

All parameters for testing are set up through the EC Screen. They can be entered through the keyboard or by using a mouse. Each channel is set up independently. A lock out provision is included to prevent changes by unauthorized persons.

Multi Screen 

• Simultaneous test results, including thresholds, for up to two channels, in polar and linear modes
• Clearly demonstrates defect signals outside the acceptable threshold levels
• Displays Rotary speed, piece number, length, and throughput speed

New C Scan Screen 

For rotary probe applications, an intuitive C Scan combines all channels and clearly displays the defect location with respect to its circumferential and longitudinal position.

Built-In Monitor 

The standard model MultiMac® SM is supplied with a built-in monitor, as shown above. The instrument can also be supplied without a built-in monitor, if requested when ordered.

Track Screen 

The Track Screen allows for a visual representation of the product, length, line speed, end suppression, flaw tracking, piece count, and output (alarm) routing. Advantages include increased quality control and decreased down time.

Chart Screen 

• Shows the linear test results for up to 2 channels at a time
• Each channel can record up to 3 charts, based on the type of thresholds
• Time, date, piece number, length and speed of the material under test are also indicated
• ­Gates can be set for OD, ID, or Sector
